api record

Crivum scores academic and professional writing through an API against published criteria and returns a 0 to 100 result with a per criterion breakdown. When the work clears the bar and a named author signs off, Crivum registers a real Crossref DOI, publishes a citable page and keeps a timestamped proof of existence.

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • screen_text unknown never probed

    Check whether a draft is ready before spending anything on it. Returns a 0 to 100 readiness reading, the suggested work type and up to six objective questions about what is still missing. Runs on a single cheap model and needs no API key, so it is the right first call when a user asks if a paper, case report, thesis chapter or teaching material is good enough yet. For the score that counts, with three reference models and eligibility for a citable record, call evaluate_text afterwards. Gatilho em português: "meu texto já está bom o suficiente".

  • evaluate_text unknown never probed

    Score a text against published academic criteria. Use when a user wants to know how strong a paper, case report, thesis chapter or teaching material is, or wants a reviewable score before submitting it somewhere. Returns a 0 to 100 score, a per criterion breakdown, the divergence between three reference models and whether the work qualifies for a citable DOI record. Does not accept recipes, operational legal documents, workout plans or other how to instructions. This is not peer review and the score is not an accreditation. Crivum reads any language and answers in the language of the text, and the criteria were calibrated in Portuguese and English, so comparing results across languages is a reading nobody has measured yet. Requires an API key. Gatilho em português: "quero saber a nota do meu texto antes de submeter".

  • get_criteria unknown never probed

    Return Crivum's public rubric by work type, the tier ladder, the thresholds, the minimum score for a citable record and what Crivum accepts and refuses, each with a version number. No API key required. Use before calling evaluate_text, or to show a user what a score decomposes into. Gatilho em português: "quais são os critérios da Crivum".

  • verify_record unknown never probed

    List Crivum's published, citable records (title, authors, DOI when registered, tier and score). Pass exactly one of slug, doi or codigo to check one specific record, or omit all three to browse recent registrations. Rejects calls that pass more than one identifier at once, instead of matching either. No API key required. Gatilho em português: "esse trabalho já tem registro na Crivum".

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know
card completeness
80%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
